Feature: Help (--help)

  In order to get standard help on how to use the application
  As a software developer and user of the application
  I want to print out its usage with syntax, description, examples, available
  global options and commands

    Usage: ls [OPTION]... [FILE]...
    List information about the FILEs (the current directory by default).
    Sort entries alphabetically if none of -cftuvSUX nor --sort is specified.

    Mandatory arguments to long options are mandatory for short options too.
      -a, --all                do not ignore entries starting with .
      -A, --almost-all         do not list implied . and ..
          --author             with -l, print the author of each file
      -b, --escape             print C-style escapes for nongraphic characters
          --block-size=SIZE    scale sizes by SIZE before printing them.  E.g.,
                                 '--block-size=M' prints sizes in units of
                                 1,048,576 bytes.  See SIZE format below.
